ANTHONY I. BENI, l' OHIO SEALING BIN'G FOB TABS Application tiledDecember 28, 1927. Serial No. 248,073.

-The present invention relates to improvements in sealing rings forpreserving jars that are provided for the purpose of hermetically sealinthe cover on the jar.

The usual ru ber gaskets that constitute the sealing rings are difficulttograsp and pull outwardly whereby to break the seal and frequently aknife or other implement must be employed for disposition between theflange on the cover the jar and the sealing ring or shoulder of the jarso that the seal can be broken in order to facilitate the removal of thecover.

One of the important objects of the pres- 1 ent invention is to providea sealing ring which is of such construction as to enable the same to bepulled outwardly whereby to break to seal and at the same time uniformlydistribute the strain around the elastic ring so that said sealing ringwill not become broken or torn.

A further object of the invention is to provide a sealing ring whereinintegral opposed lips are formed on the ring, said lips being formedwith linger engaging shoulders that are curved at their inner f: r:es topermit the lingers of the operator to readily grasp the lips andetliciently pull the sealing ring outwardly away from the jar so thatthe seal will be broken and the cover can then be readily and easilyremoved.

A still further object is to provide a sealing ring of the abovementioned character which is simple in construction, inexpensive,

strong and durable and further well adapted to the purpose for which itis designed.

Other objects and advantages of the invention will become apparent fromthe following description taken in connection with the accompanyingdrawing.

In the accompanying drawing wherein like reference charactersindicate'like parts throughout the several views:

Figure 1 is a perspective viewpf'the upper portion of an ordinary fruitjar showing my improved sealing ring in the act of being pulledoutwardly to break the seal.

Figure 2 is a top plan view of the sealing ring.

Figure 3 isa cross'sectional view therethrough, and

Figure 4 is a fragmentary detail of a modication of the lip structure.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment 0f my invention, the numeral 1 designates generallymy improved sealing ring, the same consisting of an annular body ofelast-ic material. A pair of diametrically opposed lips 2 and 3,respectively, are formed integrally with the elastic annular body andextend from the peripheral edge thereof.

A shoulder 4 is formed on the upper face of each laterally extending lipat the outer edge portion thereof andas is clearly shown in Figure 2,the inner face of each shoulder is curved to conform to the contour ofthe thumb of .the person graspin the sealing ringlin the manner asclearly s own in Figure Furthermore, the outer edge of the shoulderconforms with the contour of the shape of the outer portions of eachlip.

In Figure 4 of the drawing I have shown a modification wherein shouldersare formed on both the upper and bottom faces of each lip, saidshoulders being designated by the numerals 5 and 6, respectively, andthe inner faces of these shoulders are also curved to conform to thecontour of the four lingers and thumb. Normally, the sealing ring 1 isdisposed around the threaded neck of the fruit jar A, and the screwthreaded cover B will have its ange C engaging the upper face of thesealing ring and the bottom face of the sealing ring will be inengagement with the shoulder formed at the juncture of the threaded neckwith the body of the jar, thereby forming a hermetically sealed jar. Thelips will protrude beyond the edge of the flange so that the person canreadil grasp either or both of the lips and by pullying the sameoutwardly, the seal will be broken and the strain will be evenlydistributed around the annularmember, thus preventing the ring frombeing torn. Furthermore, the provision of the shoulders on the outeredge portions of the lips will enable a person to more eiiicient- 100Weense ly greep the lips end p the een ont- Werdly.

A sealing of the above mentioned character et ell times be positive and"g ecient in carryin out the purposes for which it is designe and due toits simpliol ity, the same can be manufactured at e very low costo Whileli have shown the preferredembodilo ment of my invention it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to A without departing from the spirit oftheinvention and the scope' of the appended claim. Having thus describedthe invention, what I claim as new and desire to secure by Letl tersPatent isz- A sealmg ring consisting of an annular bod of elasticmaterial, an integral lip projectm from the peripheral edge of theannular y, and a, shoulder formed on one face of the lip at the outeredge portion thereof, the outer edge of the shoulder being sha d toconform to the contour of the lip,

`5 the mner face of the shoulder being curved to conform to the contourof the finger or thumb of `a. person grasping the sealing ring andpulling the same outwardly.

In testimony whereof I ax my signature 3 ANTHONY M. RINI.
